Flashcards in pelvis Deck (23):
1

which PSIS is the one that is dysfunctional? the one that moves first or second

first

2

what is the purpose of the spring test

assess if sacral base has moved posterior

3

what is a positive spring test

no springing allowed (non-neutral condition)

4

what is a negative test for spring test

there is spring allowed (neutral condition)

5

what is another name for the sphinx test

backward bending test

6

what does the sphinx test point out

helps point out any asymmetric motion of the sacrum

7

what position is the patient in for sphinx test

prone

8

what must a patient do if they are in the supine position and you are evaluating anything with the hips

the patient must do a hip flop

9

what 3 things must you know for diagnosing sacral dysfunction

deep sacral sulcus, posterior/inferior ILA, spring test/sphinx test

10

when does the pelvis fuse

by mid 20s

11

what are the 3 true ligaments of the pelvis

anterior SI, interosseous, posterior SI

12

what are the 3 accessory ligaments of the pelvis

sacrotuberous, sacrospinous, iliolumbar

13

what ligament forms the greater and lesser sciatic foramen

sacrospinous

14

what are the secondary muscles of the pelvis

rectus abdominis, transverse abdominis, obliques, quadrature lumborum

15

what occurs as the acetabulum travels inferiorly

it gives an apparent increase in leg length

16

where do the transverse axes of the sacrum occur

at S2

17

what is the superior transverse axes of the sacrum involved in

respiration

18

what is the middle transverse sacral axis involved in

sacroiliac motion (bending spine)

19

what is the inferior transverse sacral axis involved in

iliosacral motion (ambulation)

20

what axis is rotation occurring around during normal gate

transverse axis

21

how does the ilium move when walking (in healthy patient)

posterior rotation during forward swing of ipsilateral leg, anterior rotation during backward swing of ipsilateral leg

22

what are the 3 true ligaments of the pelvis

anterior, interosseous, and posterior SI ligament

23

what is the accessory ligament from anterior inner iliac crest to transverse processes of L4 and L5

iliolumbar ligament
